Application led August 6, 1914. Serial No. 855,461.

T 0 all Lo/wm t may concern Be it known that l, ERNEST R. JACKSON, acitizen of the United States, residing at Mena, in the county of Polkand State of Arkansas, have invented a new and usefulHydrocarbon-Burner, of which the following is a specification.

The present invention appertains to liquid fuel or hydrocarbon burners,and aims to provide a novel and improved device of that character.

The present invention comprehends the provision of a hydro-carbon burnerembodying a unique assemblage of parts, whereby the burner structurewill be comparatively compact, substantial, inexpensive, and capable ofready assemblage and separation, and whereby the burner will beeflicient in its use.

It is also the object of this invention to provide a hydro-carbon burnerembodying a peculiar assemblage of a retort or generator and a burnerbody, to carry out the desired objects in a satisfactory manner.

lVith the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the conibination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, can be made within thescope of what is claimed, without departing from the spirit of theinvention.

The invention has been illustrated in its preferred embodiment in theaccompanying drawing, wherein z- Figure 1 is a plan view of the improvedburner, a portion of the supply pipe being broken away. Fig. 2 is alongitudinal vertical section of the burner taken on the line 2 2 ofFig. 1. Fig. 3 is a longitudinal section of the retort or generatortaken on the line 3 3 of Fig. 1. Fig. 4 is a cross section of the burnertaken on the line 4--4 of Fig. 2.

ln carrying out the present invention, there is provided a tubular orhollow cylindrical burner body 1, which has its ends open, and which ispreferably cast from suitable metal. The burner body 1 is disposedhorizontally and is provided with a plurality of rows of upper aperturesor outlet orifices 2, which are preferably surrounded by bossesopstanding from the burner body 1, as clearly seen in Figs. 2 and a. Thefront row of apertures or oriiices 2- is preferably at a lower levelthan the others, as seen in Fig. 4t.

Cast metal caps 3 and 4 are slipped or engaged over the ends of theburner body l, and are secured together by a pair of longitudinal tie ordraft rods 5 terminally en` gaged through the caps 3 and 4t and disposedadjacent the front and back sides of the burner body, as seen in Fig. 4.The tie or draft rods 5 have nuts or other securing elements engagedupon their ends, as clearly seen in the drawing, whereby the burner body1 will be clamped securely between the caps or heads 3 and 4. The caps 3and a are provided with lower legs 6 for supporting them upon a grate,or other surface upon which the burner is to be set. rlhe rims of thecaps 3 and 4 are also pr vided with upstanding standards 7 which areinclined forwardly slightly, as seen in Fig. d, and which are locatedadjacent the ends of the rear row of outlet apertures 2.

The burner body 1 is provided along its front side with an integralpriming cup or gutter 8, which is coextensive with the outlet apertures2, and which is located directly below the forward row of apertures, asseen in Fig. 1.

The cap 4 is provided with an outstanding tapered nipple 9 having theair openings or inlets 10 in its sides, and a tubular nozzle or mixingtube 11 projects axially g into the burner body 1 from the cap a, andhas its outer end threaded into the nipple 9 to communicate therewith.rlhe free end of the nipple 9 is provided with upper and lower notches12 for the purpose which will hereinafter appear.

The retort or generator for vaporizing the liquid fuel, embodies anelongated and relatively flat casting 13 disposed longitudinally abovethe rear side of the burner 1, and resting against the standards 7,screws or other securing elements 13El being engaged through thestandards 7 and taking into the end portions of the retort casting 13 toclamp the same against the standbores 14 and 15 extending therethrough,and with an inclined or diagonal bore 16 connecting opposite endportions of the bores 14 and 15. That end of the lower bore 14 adjacentthe lower end of the bore 16, is plugged or stopped up by a screw plug17, while the liquid fuel supply pipe 18 is engaged or threaded into theother end of.v the bore 14, and is provided with a suitable controllingvalve 19. The liquid fuel supply pipe 18 may lead to a tank or othersuitable source of liquid fuel, and the liquid fuel may be supplied bygravity or under pressure, which ever is desired. That end of the upperbore 15 of the retort casting adjacent the upper end of the bore 16, isstopped up by a screw plug 20 threaded thereinto, and an outlet pipe 21for the retort is threaded or otherwise engaged in the other end of thebore 15 opposite the supply pipe 18 and has a depending arm 22 seatedwithin the notches 12 of the nipple 9 to hold the arm 22 in place. Thelower end of the arm 22 is closed by a cap 23, and the outlet arm 22 isprovided with an aperture 24 coaxial with and leading into the nipple 9.

As will be apparent, the burner body 1, caps 3 and 4, and the retortbody 13 are each cast from metal, whereby they may be inexpensivelymanufactured. Furthermore, the component parts of the burner may bereadily assembled, and provide a compact and desirable structure..

In operation, when the controlling valve 1.9 is opened, the liquid fuelwill be permitted to flow into the lower longitudinal bore 14 of theretort, and a small quantity of combustible material or liquid may beplaced or poured within the priming cup or channel 8 and then ignited soas to prime the burner, it being noted that the matter within thepriming cup or channel 8 being ignited, will serve to heat the retort tothereby start the vaporization of the liquid fuel within the retort. Asthe liquid fuel becomes vaporized within the bore 14 of the retort, thesame will pass upwardly through the inclined bore 16 into the upper bore15, in which the vapor' will be superheated, and the superheated vaporwill then pass outwardly through the outlet pine 21 of the retort andthrough the aperture 24. The vapor being discharged through the nipple 9from the aperture 24, will draw air through the air inlets 10 of thenipple, and the vapor and air will then be thoroughly admixed within themixing tube or nozzle 11, and ejected into the burner body 1. 1Withinthe burner body 1, the mixture will be thoroughly agitated and will passupwardly through the outlet apertures 2 to support the flames. Theflames will then serve to continue the vaporization of the `liquid fuelwithin the retort,l which retort will be heated by the iiames and theames will also serve to heat the boiler, furnace or other structure towhich the device is applied. The other advantages and capabilities ofthe present invention will be obvious to those versed in the art,without extensive comment being necessary.

Having thus described the invention, what is claimed as new is l. In ahydro-carbon burner, a hollow burner body having upper outlets, capsengaged over the ends of the burner body, one cap having an outstandingnipple provided with an air inlet, a retort secured to the said caps,and an outlet pipe connected to the retort and having an arm providedwith an aperture communicating with the nipple, the free end of thenipple having notches receiving the said arm.

2. In a hydro-carbon burner, a hollow burner body having upper outletsand an elongated priming cup along its forward side, caps slipped overthe ends of the burner body and having standards, tie rods connectingthe caps, one cap having an outstanding nipple provided with air inletsand having notches at its free end, a nozzle threaded into said nippleand projecting into the burner body. a retort secured to the saidstandards above the rear side of the burner body and having borestherein, and an outlet pipe secured to the retort to com municate withthe bores thereof and having an arm seated in the said notches of thenipple and provided with an aperture communicating with the nipple.

In testimony that I claim the foregoing as my own, I have hereto atlixedmy signature in the presence of two witnesses.
